Base: v2 ← Head: asciicast-v2

📄 Description

The ideas behind asciicast v2 format are:

enable live, incremental writing to a file during recording (with v1
format the final recording JSON can only be written as a whole after finishing
the recording session),
allow the players to start the playback as soon as they read the meta-data
line (contrary to v1 format which requires reading the whole file), without need to buffer whole recording in memory,
use the same data representation whether you're recording to a file or streaming via UNIX pipe or WebSocket.
